PRODUCT SHOWCASE: Sinumerik Gives Performance Boost for CNC Hardware


For the high-end machine tool market, Siemens introduces version 4.7 of the Sinumerik Operate software, featuring new, more powerful CPUs and 15- and 19-inch “Blackline” panels in widescreen format for the Sinumerik 840D sl CNC. The new 7×0.3B PN processors are Profinet-compatible NCUs (numerical control units). The new processor technology, for example the NCU 730.3B PN, is up to 15 percent more powerful than the previously used components. The result is shorter program runtimes, faster simulation, and overall faster operation. The new technology, exemplified by the 720.3B PN and 730.3B PN NCUs, also consumes up to 50 percent less power, which results in the processors generating less heat.

The basic configurations of the 7×0.3B PN-CPUs for the Sinumerik 840D sl CNC already have 10 MB of buffered user memory as standard for part programs, plus a 2 GB working memory (DRAM). The part program memory can be expanded up to 22 MB, depending on the particular processor model. In most cases, automatic adaptation of the drivers enables integration of the new NCUs into existing machines and applications, without modifying the software. The new, long-term availability of this NCU processor technology offers a secure future for newly developed machines —– both in their subsequent technology developments and in the long-term availability of Siemens spare part components.

The new 15- and 19-inch “Blackline” panels are widescreen format touch screen CNCs. They are mainly characterized by good legibility, simple operation, and a long service life. The technical basis of the display is a capacitive sensor system that supports touch operation, even when gloves are worn by the operator. The panels are designed for degree of protection IP66 and are especially rugged. For example, the 15-inch panel is approved for vibration accelerations up to 2 g. Both these new devices have an integrated thin client unit (TCU) and are connected to the Sinumerik via Ethernet.

These new NCUs and touch panels expand the Siemens range of CNC systems and products. By using the new hardware components, builders can increase both the performance and ease of operation on their machines.
